NAME
       cimag, cimagf, cimagl - get imaginary part of a complex number

LIBRARY
       Math library (libm, -lm)

SYNOPSIS
       #include <complex.h>

       double cimag(double complex z);
       float cimagf(float complex z);
       long double cimagl(long double complex z);

DESCRIPTION
       These functions return the imaginary part of the complex number z.

       One has:

           z = creal(z) + I * cimag(z)

VERSIONS
       These functions were added in glibc 2.1.
